Abstract
A way and a system for invoking a method in an object-oriented language which is so arranged that when a predetermined method for a first whole object is invoked, two instance variables of the first whole object maintain an exclusive relationship while the exclusive relationship is also satisfied between first and second part objects. In such an arrangement, when a message is sent from a second whole object to the first part object and the exclusive relationship cannot be satisfied between the first and second part objects, a daemon method for the first whole object is invoked to send a message from the first whole object to the second part object, thereby maintaining the exclusive relationship between the first and second part objects.
